SPECIFICATION forming part of Letters Patent No. 628,800, dated July 11,i899. Application filed March 1'1, 1899. Serial No. 708,695. (No model.)

To wZZ whom it may concern:

Be it known that I, J ULIUS JOHN HELLING, a citizen of the UnitedStates, residing at Union, in the county of Franklin and State ofMissouri, have invented a new and useful Ditch- Grader, of which thefollowing is a specification.

My invention relates to machines for grading water ditches or drains,but which with but slight, if any, alteration may be adapted to otherkinds of operating.

The object of the invention is to furnish a cheap, simple, and efficientmachine of this class in which will be provided simple means foraccomplishing all the movements and adjustments of parts necessary tothe effectual operation of the machine.

My invention consists in the improved construction, arrangement, andcombination of parts hereinafter fully described and afterwardspecifically pointed out in the appended claims. .1 t

In order to enable others skilled in the art to which my invention mostnearly appertains to make and use the same, I will now proceed todescribe its construction and operation in connection with theaccompanying drawings, forming a part hereof, in which- Figurel is aperspective view illustrating a machine constructed in accordance withmy invention. Fig. 2 is a top plan view thereof. Fig.6 is a detailperspective View showing the front end of the scraper and itsconnections. Fig. 4 is a detail view of the hookbracket. illustrated inFig. 3 detached. Fig. 5 is a detail view illustrating the manner ofconnecting one of the connecting-rods to the axle, and Fig. 6 is adetail view illustrating the connection of the opposite end of the samerod to the rear end of the scraper.

Like numerals of reference mark the same parts wherever they occur inthe various figures of the drawings.

Referring to the drawings by numerals, 1O 10 indicate the wheels uponwhich the machine is supported, and 11 the axle journaled in saidwheels, the axle being cranked downward at each end to raise the framewithout increasing the diameter of the Wheels.

12 indicates the main framebeam, which also serves as the tongue and issecured to the axle 11 by bolt 13.

14 indicates a second frame-beam, which is secured to beam 12 at aconsiderable dis tance in front of the axle by means of bolt 15, extendslaterally and backward, and is secured to the axle by bolt 16, thusforming, with axle 11 and beam 12, a triangular rigidlybraced frame, thebeam 12 standing at right angles to the axle.

17 indicates an eyebolt depending from the beam 12 at a point in frontof its junction with beam 14, through the eye 0; which passes an eyebolt18, which extends rearward ly and affords a substantially universaljoint, with the angle of a metallic V-shaped frame horizontallysupported under the main frame and consisting of a long bar 19 and ashort bar 20. The forward end of each of these bars is turned downward,as. at 21 22, the end of the short bar being connected by means of abolt 23 with a scraper 24: near its forward end and the end of the longbar by means of a bolt 24 with the scraper near its rear end, thescraper being thus supported at front and rear by the V-shaped frame. u

The bars 19 and 20, at their rear ends, are adj ustably suspended fromthe main frame, and for this purpose the following mechanism isprovided, viz: 25 indicates a bracket rigidly secured to the frame-beam12, the upper end of bracket being formed in a curved rack 26. At thecenter of the curve of the rack is pivoted an elbow-shaped hand-lever27, carrying a spring-pawl 28 to engage the rack and a rod 29, pivotallydepending from its short arm and universally jointed at'its lower end tothe hook 30 of an angular bracket 31, secured by bolt 32 to end 22 ofshort bar 20 and by bolt 33 to the scraper. The bolt 16, which securesthe beam 1% to the axle, also secures a bracket 34 to beam 14, and thisbracket is formed into a curved rack 35 at its upper end. At the centerof the curve of the rack is pivoted an elbow hand-lever 36, having aspring-pawl 37 to engage the rack, and at the end of its short arm a rod38'is pivotally connected, the lower end of this rod being universallyjointed at 39 to the arm 19. The bolt 24, which connects bar 19 to thescraper, also serves to secure a hook 40, in which is engaged one end ofa brace-rod 41, the opposite end being engaged in an eyebolt 41,depending from the-axle at the lower angle of one of its cranked ends.

' An angular brace 42 on the under side of the front end of the scraper,Fig. 3, serves to stiffen and strengthen the scraper at this point, andan extension-plate secured to the rear end of the scraper on bolt 44 byhand-nut 45,serves to lengthen the scraper when desired.

The normal position of the scraper is at about an angle of forty-fivedegrees from the line of draft, and by means of the mechanism describedeither or both ends of the scraper may be adjusted at will, thehand-levers being on opposite sides and within easy reach of the driverseated in seat 46, supportedcby spring-bar 47, secured to the foot-board48, said foot-board being bolted or otherwise secured upon the two mainframe-beams. The whiffletree-hook will be secured in the eye of bolt 18.

My invention is extremely simple in construction and economical toconstruct, so that it may be made cheap enough to be within the reach ofany ordinary farmer who has ditches to keep clean and graded.

Having thus fully described my invention,

. what I claim as new, and desire to secure by Letters Patent ofthe'United States, is

1. In a grading-machine, the combination with the wheels axle andframe-beams supported therefrom, of a 'V-shaped metallic frame suspendedat its forward angle below the main frame-beam, a scraper arrangeddiagonally and adjustably suspended, at its front and rear ends from thebars of the V- shaped frame, and a diagonal brace-rod connecting therear end of the scraper with the opposite end of the axle, substantiallyas described.

2; In a grading-machine the combination with the diagonally-placedscraper and the axle, of the supporting-bar 20, bolted to the scrapernear its forward end, the main frame supported on the axle, the rod 29adjustably suspended from said main frame and the angular hooked bracket31 connected to said rod, the scraper and the bar 20, substantially asdescribed.

3. In a grading-machine, the combination with the scraper, thesupporting-bar 21 and the axle, of. the hook 40, the bolt 24 connectingthe scraper, rod 21 and said hook, the eyebolt 41 secured in the axle,and the bracerod connecting book and eyebolt 41 substantially asdescribed.

4. In a grading-machine the combination with the wheels and axle of themain tonguebeam bolted on top the axle the brace-beam bolted to the sideof the tongue-beam and on top the axle, the V-shaped metallic framecomprising a long and a short bar with their angle to the front, aneyebolt depending from the tongue-beam on front of said angle, a secondeyebolt through the eye of the first and l the angle of said frame, thescraper diagonally located below the frames, and adjustable connectionbetween the forward end of the scraper and the short bar, and the rearend of the scraper and the long bar, substantially as and for thepurpose set forth.
